一，工具集成
Logcat是開發(fā)者必備的工具，調(diào)試app時(shí)的閃退，異常，等問題都可以在這里看到。
Android Logcat包是在Unity Editor中顯示來自Android設(shè)備的堆棧跟蹤和日志等消息。
1.1 注意事項(xiàng)
Android Logcat軟件包需要Unity 2019.4或更高版本以及Android支持模塊。需要添加Android模塊：
導(dǎo)入前需要注意：確保你的工程已加載Android模塊，并且可以切到Android平臺。
確認(rèn)后在“build Settings”窗口中切換到Android構(gòu)建目標(biāo)。
1.2 導(dǎo)入插件
在Package Manager(Window” --> PackageManager)界面中導(dǎo)入：
插件簡介：
Android Logcat軟件包支持：
Android：日志消息
Android：應(yīng)用程序內(nèi)存統(tǒng)計(jì)
Android：屏幕捕獲
Android：屏幕記錄器
Stacktrace：實(shí)用程序
可以通過“Window > Analysis > Android Logcat ”在Unity Editor中訪問該窗口。
窗口打開快捷鍵：Windows 按“Alt+6”；macOS “Option+6”
二，連接設(shè)備
Android Logcat軟件包支持USB和無線連接。本節(jié)介紹如何將Android設(shè)備連接到Android Logcat窗口。
2.1 使用USB連接
當(dāng)您打開Android Logcat窗口時(shí)，Unity會自動將任何USB連接的Android設(shè)備添加到設(shè)備列表中。
手機(jī)連接上USB之后，需要選擇：傳輸文件。若沒有此選項(xiàng)，則需要打開開發(fā)者模式。
PS: 在手機(jī)版本上多次點(diǎn)擊才可以喚醒出開發(fā)者模式，再次點(diǎn)擊則有吐司提示您已處于開發(fā)者模式，這時(shí)再去更多設(shè)置中去找開發(fā)者模式并開啟即可。
檢測上之后，即可在窗口中看到實(shí)時(shí)日志了：

2.2 無線連接
要將Android設(shè)備連接到Android Logcat窗口：
無線連接，還是得先使用2.1方式使用USB鏈接一下，然后打開Android Logcat窗口，從工具欄中，選擇“設(shè)備選擇器”。
選擇其他連接選項(xiàng)：
在打開的窗口中，找到對應(yīng)設(shè)備點(diǎn)擊Connect：
連接成功提示：（不使用USB方式鏈接，直接輸入IP地址，總是鏈接失敗，不知道為什么[\疑惑]）
連接成功后，拔掉USB連接，就可以在可用設(shè)備窗口，找到Wifi鏈接的了：
PS：一次只能連接到一個設(shè)備。要選擇要連接的設(shè)備，請使用Android Logcat窗口中的設(shè)備列表。此列表包含已連接設(shè)備的設(shè)備ID。
可以看到實(shí)時(shí)日志了：
若需要斷開連接，可以在連接窗口對應(yīng)設(shè)備后點(diǎn)擊“Disconnect”：
再次連接，直接點(diǎn)最下面的Connect鏈接，即可鏈接成功。
三，實(shí)用功能介紹
3.1 通用介紹
1.篩選包名查看日志
點(diǎn)擊No Filter，在彈出的下拉菜單中，即可選擇當(dāng)前運(yùn)行應(yīng)用的包名，進(jìn)行查看當(dāng)前應(yīng)用的相關(guān)日志：
2.篩選日志信息
Logcat工具支持在搜索框輸入正則表達(dá)式檢索和區(qū)分大小寫功能:
3.Reconnect重新連接，Disconnect斷開鏈接
當(dāng)我們出現(xiàn)一個問題，需要查看日志時(shí)，為了防止日志太多將需要查看的日志刷過去，則可以點(diǎn)擊Disconnect斷開鏈接，停止捕獲更新日志信息。需要再次查看日志時(shí)，點(diǎn)擊Reconnect重新連接。
3.2 堆棧跟蹤工具 – 解析Bugly捕獲報(bào)錯
在Tools下拉菜單下選擇Stacktrace Utility 可以打開工具面板：
準(zhǔn)備工作：指定符號表）
在Project Setting面板 -> Analysis -> Android Logcat Settings 中設(shè)置：
PS：打包時(shí)用的哪個就導(dǎo)入哪個，看你打包時(shí)的工程設(shè)置：Player -> Configuration
image.png
若不指定會在解析時(shí)報(bào)錯提示：
At least one symbol path needs to be specified.
Click Configure Symbol Paths and add the necessary symbol path.
舉個例子：解析Bugly捕獲報(bào)錯
操作步驟：復(fù)制Bugly報(bào)錯到工具Original界面，然后點(diǎn)擊Resolve Stacktraces 即可：
